Abstract: “Road development in Taiwan has progressed to the maintenance and management stages of its life cycle. Therefore, it is necessary to introduce information technology approaches to assist in pavement management activities. Belief-function theory (BFT), otherwise known as the Dempster-Shafer theory of evidence, has been advocated by many as a method of representing uncertain, incomplete, and imprecise evidence of a system’s knowledge base. BFT is still scarce in applications for the construction industry and even pavement management until now. This paper applied BFT to pavement management, in particular to the pavement maintenance and rehabilitation (M and R) activities. One case study was conducted using BFT to understand whether M and R activities need to be implemented for a pavement section. This study completed a preliminary study of BFT to promote efficiency in pavement management.”
